Compressed Natural Gas (CNG) Dual Fuel Engines

As of this spring 2008, US supply of fossil fuel and the price of a barrel of oil is in the front of most americans minds.

I have been hearing about the proposal to switch car, truck(passenger, medium, and heavy) and even marine transportation to Compressed Natural Gas with a LPG (Gasoline or Diesel Pilot) or Dual Fuel.

I believe the Asian and South American Auto Makers and Engine Makers are way ahead of the United States if such a switch is to happen.

I beggining to feel strongly, that this is a best choice. Engines that can run on a mixture and could be run on one or the other in some combination...........depending on which market was trying to monopolize or short the supply of the other.

Natural Gas is Sovereign to most continents.........The United State process Hundreds of Billions of cubic feet a day and we only use 25 billion Cubic feet a year.

Please Chevy, Ford, GMC, Jeep, Catapillar.......Cummins........get these engines as an option ....soon or we will have to buy from an asian supplier

You're absolutely correct Rockster22. More people should take CNG as an automotive fuel seriously.

By the way, welcome to the forums!

Dozens of huge cities are already using CNG for public transport. New Deli off all places is now completely CNG for ALL public transport. If they can do it, why can't the big American big cities do this also? California is the only one taking the CNG seriously, and using it successfully. Wish that the rest of the country could do the same.

Hey, at least Chattanooga has recently got all Electric Shuttles and Buses. Now just need to get the Taxi's on CNG!!!

Mecedes-Benz, has planned to set up a production base of vehicles using bi-fuel technology that can run either on regular gasoline or natural gas in Thailand.

In the new plant Mercedes will be manufacturing--among other planned models--the E 200 NGT which made its debut on Germany's roads in the spring of last year. The variant of the popular E Class sedan cuts emissions by 20%.As well as making it one of the most cost-effective models in the Mercedes range, the 120-kW/163-hp four-cylinder engine under the bonnet of the bi fuel E 200 NGT also makes it the most powerful natural-gas-driven saloon currently in production. Operating mode can be switched conveniently at the touch of a button.

At present, Thailand operates 58 natural gas (Compressed Natural Gas or CNG) service stations. It plans to increase the number to 160 next year and 740 nationwide in 2010.

The number of vehicles using natural gas in Thailand now total 500,000 units with the consumption of 365 million cubit feet per day.

To promote the consumption, the Thai government will reduce an excise tax on natural gas vehicles (using either CNG or LNG) by 10 per cent to 20 per cent and give an import tariff exemption for NGV cylinders and other related equipment

Rockster welcome.We have had a number of posts on CNG & LPG and other fuels lately and it is amazing that in the world there are over 7 million natural gas running autos and only 1,500 are here State Side...

LAS VEGAS – Sterling Truck Corporation has rolled out a new natural gas (NG)-fueled tractor. The Sterling Set-Back 113 fueled with Natural Gas is ideal for port operations, as well as natural gas utilities and municipalities. An OEM factory-built product, this truck is powered by the Cummins Westport ISL G.

Natural gas technology can save an estimated $6,000 in annual fuel and operating costs per truck. Customers in states such as California will also benefit from tax incentives for alternative-fuel vehicles. Fuel providers take advantage of these incentives, too, which means that accessibility to NG fuel is on the rise.

“Due to deterioration in air quality, the Ports of Los Angeles and Long Beach have embraced the use of alternative fuels in commercial vehicles. At the same time, utility companies and municipalities throughout North America have shown increased interest in green transportation technology,” said Richard Shearing, manager of product strategy for Sterling Truck Corporation. “By introducing the Set-Back 113 with Natural Gas, we’re giving our customers a hard-working truck that reduces both costs and environmental emissions.”

The Cummins Westport ISL G, an 8.9L stoichiometric cooled-exhaust gas recirculation (EGR) engine, offers the lowest emissions available in the industry without sacrificing top-level performance and efficiency, the company said.

Available in ratings up to 320 hp, the ISL G already meets EPA 2010 standards with 85 percent lower NOx emissions than the C Gas Plus engine and features the highest power-to-weight ratio in class with an optimized turbocharger. The ISL G also features a maintenance-free exhaust system with a three-way catalyst (TWC). No further technology or after treatment will be required to meet 2010 emissions standards.

You can't destroy matter, just change it. I think you mean that Natural Gas creates energy when it's combusted. It also takes energy to recycle or dispose of batteries in this case (cause you can indeed destroy a battery).

I feel a CNG Dual-Fuel (gas/diesel) follows the "Keep It Simple S#$$@" rule.

The less complex a company can make a CNG vehicle the better. This is a vehicle that is hardy robust and could work on either fuel you would find in the most remote locations. Natural Gas right out of the pipe if you were in a tight spot.

This is why it is being accepted in less luxurious countries.

This would be a car or truck or boat engine system that would be easy to work on an would be around so that all countries would have access to keep it running.

The duality or Tri-ality would be better where it could run on three common fuels found around the globe. But, now I am being wishful

My uncle (huge hippy, and was back in the 60's as well) has an old Ford f150 that runs on propane or gasoline.

I would like to see more of this in our semi fleets here in the U.S. It could potentially save the companies and the owner/operators lots of money. Then that savings could be passed down to us consumers.
